▎ 摘　　要

Graphene nanoplatelets have been synthesized by ball milling of synthetic graphite and its structural features studied by x-ray analysis using Mo K-alpha radiation followed by the proposal of a possible molecular arrangement using AVOGADRO(R) software. Additional characterization using complementary techniques was also performed. The radial and total distribution functions of the coordination number, as well as atomic distances within short-range order, revealed that oxygen atoms were incorporated into the material produced after 24 h of grinding. The structural disorder parameter (xi) was found to be similar to 3.5, as well as superposition between the second and third coordination spheres (r similar to 2.4 x 10(-1) nm), which can be attributed to the presence of oxygen atoms, as suggested by localized defects.
